Look, what Trump has done with tariffs is considered a bad way of doing things. Reagan said it and almost every economist that I have ever heard or read have said the same thing. Trump is not using his head and "in my opinion", he did not get Xi to do anything. It was Trump backing off because of the response he got to the tariffs on China going up to 145% and China raising theirs to 125%.
Trump is the one that wanted to fix the problem he created. Xi simply went along because it made economic sense. Nonetheless, he made it very clear that he was not going to back down from a fight. He is not a liar and Trump is, meaning I believe what Xi said and don't believe Trump's lie that it was Xi that asked to talk about a tariff solution.
The excuse given by Trump that this raising and then lowering the tariffs was a plan all along, is bullshit. Trump went overboard and the response from all Americans (including many of his own supporters) scared the hell out of him and he flip-flopped, which is something he has done many times before.
Xi is an Autocrat and a VERY strong one that will not back off and cower as he would be thrown out by his own people if he ever did that. If you know anything about Chinese culture, is that they do not believe in any kind of weakness.
This was all Trump backing down
